Retinopathy was considered present when at least one microaneurysm, hemorrhage, or hard exudate was present minimal nonproliferative retinopathy or occurred in combination with cotton-wool exudates, venous beading, or intraretinal microvascular abnormalities moderate nonproliferative retinopathy or, in case of neovascularization, fibrous proliferation or laser coagulation scars detected by photography or ophthalmoscopy, according to the classification that was used in the EURODIAB EUROpe and DIABetes study.
In each subject, the retinopathy level of the worst eye, according to ophthalmoscopy or fundus photography, was scored. In case of discrepancies between ophthalmoscopy and photography, ophthalmoscopic findings were corrected if corresponding photographically visible retinal lesions seemed to be symptoms of other underlying pathological conditions.
Fasting and 2-hour postload venous plasma glucose levels were determined with a glucose dehydrogenase method Merck, Darmstadt, Germany. For statistical analyses, the mean of 2 fasting and 2 two-hour glucose levels was used.
Subjects were classified into 3 categories NGM, IGM, or DM , in accordance with the World Health Organization criteria. Glycosylated hemoglobin and lipid levels were determined in the fasting blood sample during the first OGTT. The Hb A 1c level was determined by ion-exchange high-performance liquid chromatography Modular Diabetes Monitoring system; Bio-Rad, Veenendaal, the Netherlands normal range, 4.
Total cholesterol, high-density lipoprotein HDL cholesterol after precipitation of the low- and very low-density proteins , and triglycerides were measured by enzymatic techniques Boehringer-Mannheim, Mannheim, Germany. The non-HDL cholesterol level was calculated by subtracting the HDL cholesterol level from the total cholesterol level.
The non-HDL cholesterol level, which includes the low-density lipoprotein cholesterol level and the very low-density lipoprotein remnants, was chosen because it may be a more reliable predictor for mortality from cardiovascular disease than low-density lipoprotein cholesterol level alone. The average of 4 measurements was used for analysis.
Height, weight, body mass index BMI , and waist-hip ratio WHR were determined to assess the presence of obesity and fat distribution. Information on smoking behavior and use of medication was obtained from a questionnaire completed by the participants.
The cumulative incidence of retinopathy was calculated in categories of glucose metabolism. The baseline characteristics of individuals with retinopathy at follow-up were compared with those of individuals who had not developed retinopathy, by using a t test, a χ 2 test with continuity correction, or a Mann-Whitney test in case of a skewed distribution triglyceride levels.
The univariate association of lipid levels, obesity, and smoking with retinopathy was investigated by calculating ORs for tertiles of triglycerides; total, HDL, and non-HDL cholesterol levels; BMI; and WHR compared with the lowest tertile, and for smokers and ex-smokers compared with never smokers.
Tertiles of determinants were analyzed to evaluate possible linear trends. Odds ratios were adjusted for age and sex and subsequently for hypertension and glucose metabolism glucose metabolism category or Hb A 1c level. Hypertension was chosen for adjustment, because it combined systolic and diastolic blood pressure measurements and the use of antihypertensive medication in one variable.
To investigate the effect of DM duration, the OR for incident retinopathy was calculated per year with DM in individuals with known DM.
In all analyses, Statistical Product and Service Solutions software, version Twenty-seven Twenty-four people had minimal nonproliferative retinopathy, and one individual had moderate nonproliferative retinopathy; 2 people were treated with photocoagulation.
For baseline characteristics, individuals who developed retinopathy had a higher mean age, Hb A 1c level, systolic blood pressure, WHR, and waist circumference, and they more frequently had hypertension, than individuals who did not develop retinopathy Table 1. The cumulative incidence of retinopathy was similar for men and women, and was highest in those aged 60 to 69 years Table 2.
The cumulative incidence increased from 6. A univariate logistic regression analysis showed higher ORs for the development of retinopathy in older persons Table 2.
The crude ORs for retinopathy were 2. Risk also increased with Hb A 1c level, particularly for those in the highest tertile of Hb A 1c level, and more than doubled in individuals with hypertension compared with individuals without hypertension Table 2. After adjustment for age and sex, and for age, sex, glucose metabolism category, and hypertension, in multivariate models, the ORs did not change considerably.
When we limited the analyses to the nondiabetic subjects, the OR for those in the highest tertile of Hb A 1c level compared with those in the lowest tertile was 3. No associations were observed between BMI, serum triglycerides, and total, HDL, and non-HDL cholesterol levels and incident retinopathy Table 4.
The ORs for retinopathy were significantly higher for those in the higher tertiles of WHR, which did not change after adjustment for age, sex, Hb A 1c level, and hypertension Table 4.
Cigarette smokers and ex-smokers had higher, but nonsignificant, ORs for incident retinopathy than never smokers, particularly after adjustment for age, sex, Hb A 1c level, and hypertension. When we limited the analyses to the nondiabetic subjects, comparable results were observed data not shown.
Regarding DM duration, the OR for incident retinopathy was 1. Not only patients with type 2 DM, but elderly individuals with IGM and NGM in general, have a substantial risk of developing retinopathy.
Our findings indicate that a high Hb A 1c level, hypertension, and a high WHR are determinants of the incidence of retinopathy. Little research has been performed on the incidence of diabetic retinopathy and its association with cardiovascular risk factors in populations, including nondiabetic people as well.
To our knowledge, only 2 studies describe the incidence of retinopathy in nondiabetic subjects. The Beaver Dam Eye Study 17 reports a 5-year incidence of 6. In the present study, the incidence of retinopathy was comparable in men and women, in accordance with findings in diabetic patients.
Our study confirmed the well-known positive association between Hb A 1c level and retinopathy. The estimated risk for developing retinopathy after 10 years in individuals with hypertension was more than 2 times as high as in individuals without hypertension, which remained after adjustment for age, sex, and glucose metabolism category.
This is in line with previous findings of incident retinopathy in studies 6 , 7 , 9 , 13 of diabetic patients and in the 2 studies 16 , 17 that included nondiabetic individuals.
Type 2 DM is often associated with dyslipidemia, including elevated serum triglyceride levels and low HDL cholesterol levels. The present study did not find a statistically significant association between serum triglyceride and total, HDL, and non-HDL cholesterol levels and the development of retinopathy.
Associations between cholesterol or triglyceride levels and the incidence of retinopathy, although not always statistically significant in multivariate risk models, were described in studies 7 , 12 , 15 , 23 that included diabetic patients.
Cross-sectional data 24 , 25 have shown that hard exudates in particular are associated with elevated cholesterol levels. The WHR is an indicator for central obesity and is associated with insulin resistance.
In particular, a large waist circumference seems to play a role, because the mean hip circumference did not differ much between individuals with and without retinopathy Table 1.
The WHR was also an independent risk factor in the diabetic patients in the EURODIAB study. A positive association between BMI and retinopathy was found in the Diabetes Control and Complications Trial 4 cohort of patients with type 1 DM, but a negative association was found in diabetic Pima Indians.
The present study mainly considered early phases of retinopathy. Retinal hemorrhages and exudates at this stage could be the first symptoms of hypertensive retinopathy, during which the vasoconstrictive phase is not expressed. However, independent associations of hypertension were also found with proliferative retinopathy in diabetic populations.
In addition, Hb A 1c level and WHR were risk factors in the nondiabetic individuals. Similar to other longitudinal cohort studies with relatively older populations, the associations between baseline determinants and retinopathy may be underestimated as a result of competing morbidity and mortality.
One of the limitations of this study is the relatively small number of cases. Therefore, only the strongest associations with retinopathy are expected to be detected. Also, there was a rather high nonparticipation rate of There may be several possible explanations.
First, in contrast to previous population studies of the to year-old population, two thirds of our original selected subcohort had IGM or DM at baseline.
We observed that health had considerably deteriorated in these groups, as also indicated by the high mortality of Furthermore, the present follow-up medical examination was rather extensive, and included several visits to the research center. This may have been considered too demanding, because the nonparticipants, in general, were less healthy, had already visited hospitals or health care centers more often, or had problems with mobility.
The selection due to morbidity and mortality may also be an explanation for the relatively lower ORs for retinopathy in the highest age group. In conclusion, this study shows that a higher Hb A 1c level, hypertension, and abdominal obesity, as indicated by a high WHR, are determinants for the development of retinopathy.
Diabetic retinopathy is an Electrolytes and mineral balance condition that Diabetic retinopathy risk factors retinopayhy vision loss and blindness in retinooathy who have diabetes. It affects blood vessels in the retina the light-sensitive Diabetjc of tissue in the back of your eye. Diabetic retinopathy may not have any symptoms at first — but finding it early can help you take steps to protect your vision. Managing your diabetes — by staying physically active, eating healthy, and taking your medicine — can also help you prevent or delay vision loss. Diabetic retinopathy is the most common cause of vision loss for people with diabetes. But diabetes can also make you more likely to develop several other eye conditions:. Diabetic retinopathy is a Diabetic retinopathy risk factors sight-threatening Diabetic retinopathy risk factors of diabetes. Diabetes interferes with the Hunger and health ability to use and store Diabrtic glucose. The Diabdtic is characterized by eetinopathy much sugar in the blood, which can cause damage throughout the body, including the eyes. Over time, diabetes damages small blood vessels throughout the body, including the retina. Diabetic retinopathy occurs when these tiny blood vessels leak blood and other fluids. This causes the retinal tissue to swell, resulting in cloudy or blurred vision.A rteinopathy list of the study group Gestational diabetes breastfeeding be found in the Facors Data online.

Diabetic retinopathy risk factors, the importance of modifiable risk factors for these vision-threatening stages of DR remains unclear. Generating a broader and more precise estimate of the prevalence of DR and its relationship with major modifiable risk factors, specifically for vision-threatening DR VTDRis crucial for guiding public health education and optimal clinical management of diabetes.
We therefore conducted an individual participant analysis pooling population-based studies from the U. We first performed a systematic literature review to identify all population-based studies that had ascertained DR from fundus retinal photographs.
Irrelevant and duplicate citations were excluded after a review of the titles and abstracts. The full texts of the remaining articles were reviewed to ensure studies met inclusion and exclusion criteria.
In addition, we manually reviewed bibliographies of included articles and consulted with colleagues to identify other potentially relevant population-based studies that had assessed DR from fundus photographs but which may not have published results or in which grading for DR was still ongoing.
Two investigators J. independently selected the studies for inclusion. Disagreements between the two were resolved by adjudication with two additional reviewers S. We identified 58 population-based studies in which fundus photographs were potentially assessed for DR.
Principal investigators of these identified studies were then invited for collaboration in this individual participant meta-analysis. We requested individual participant data regarding presence and severity of DR, DME status, age, sex, ethnicity, diabetes type and duration, hemoglobin A 1c HbA 1csystolic and diastolic blood pressure, lipid profile, cigarette smoking status, BMI, and current use of diabetes, antihypertensive, and lipid-lowering medications.
Investigators from 35 of the 58 identified studies provided data for this analysis Table 1. Investigators of the remaining 23 studies could not or did not want to participate, or did not respond to repeated invitations. All studies had institutional board review approval and provided appropriately deidentified data for analysis.
Retinal photography was performed in all 35 studies according to standardized protocols. Most of the studies graded for DR using the Early Treatment Diabetic Retinopathy Scale ETDRS and its modification or the American Academy of Ophthalmology AAO International Clinical Diabetic Retinopathy Disease Severity Scale Table 1.
DME was defined as absent or present. The four primary outcomes for this study were based on the severity in the worse eye or of the single eye that was photographed. These composite outcomes serve as the primary outcomes for this report, which respectively, indicate presence of any DR and severe DR likely to result in vision loss if left untreated.
Not all studies reported information on diabetes type. If data on age at diagnosis of diabetes were available in these studies, participants were classified as type 1 if they were diagnosed before age 30 years and as type 2 if they were diagnosed with diabetes after age 30 years, as previously used in one study 7.
Study methodology and heterogeneity were assessed independently by two investigators J. Any disagreement was settled by consensus or adjudication with a third reviewer S. Studies were assessed for a list of attributes as defined in Supplementary Table 1.
Data from each study were checked for consistency in variable definition before pooling, and where appropriate, data were recategorized according to a common definition.
Asians were further subdivided into Chinese or Japanese origin, and South Asian Indian, Malay, South Indian, Thai, etc. Study-specific and pooled-data estimates of the prevalence of any DR, PDR, DME, and VTDR were directly age-standardized to the world diabetes population aged 20—79 years 8 using age strata 20—39, 40—59, and 60—79 years.
Initial analyses included data from all 35 studies, and subsequent analyses were performed using only data from studies with similar methodologies and outcome definitions i.
Results from the latter analyses are presented throughout this report because of their similar methodologies. Poisson regression models with robust error variance were used to estimate relative risks for DR, PDR, DME, and VTDR by categories of risk factors e. Including sex in regression models generally did not improve the model fit and did not appreciably alter the results.
The total number of patients with diabetes with DR aged between 20 and 79 years was estimated by multiplying the country-specific totals of people with diabetes sourced from Diabetes Atlas by our pooled racial group—specific rates of DR using the most predominant racial group per country; for example, in Brazil, where All analyses were undertaken using Stata Intercooled Data were collated from 22, individuals from 35 studies in the U.
The mean age was Summary characteristics of the diabetic participants from each of the included studies are presented in Table 1 and Supplementary Table 2.
Analyses of these 35 studies showed that the overall age-standardized prevalence of any DR was Analyses confined to studies with similar methodologies and rigorous outcome definitions showed that the age-standardized prevalence was There was no discernible sex difference in the prevalence of any DR or for PDR, DME, or VTDR.
Extrapolating these prevalence rates to the world diabetes population, we estimate that Age-standardized prevalence of DR in diabetic subjects aged 20—79 years, using studies with similar methodologies and ophthalmologic definitions.
Table 3 reports the age-standardized prevalence of any DR by retinopathy risk factors and other subgroups of interest. The prevalence of any DR varied across ethnic groups and was highest among African Americans and lowest among Asians.
The prevalence of any DR increased with diabetes duration Similar relationships were also evident in the prevalence patterns of PDR, DME, and VTDR.
Age-standardized prevalence of DR by subgroups of interest, in diabetic subjects aged 20—79 years, using studies with similar methodologies and ophthalmologic definitions. Age-standardized prevalence of DR by diabetes type and duration, in diabetic subjects aged 20—79 years, using studies with similar methodologies and ophthalmologic definitions.
This study provides a global estimate of the prevalence of DR and the severe stages of DR PDR, DME using individual-level data from population-based studies worldwide. On the basis of the data from all 35 studies on more than 20, participants with diabetes, we estimated that among individuals with diabetes, the overall prevalence of any DR was Analyses confined only to studies with similar methodologies and ophthalmologic definitions showed that the age-standardized prevalence of any DR was The prevalence estimates of any DR and VTDR were similar in men and women and were highest in African Americans and lowest in Asians.
Prevalence rates were substantially higher in those with type 1 diabetes and increased with duration of diabetes, and values for HbA 1cblood pressure, and cholesterol.
Extrapolated to the world diabetes population inwe estimate that approximately 93 million may have some DR, and 28 million may have sight-threatening stages of DR. The prevalence of DR has been previously reported in a number of population-based samples 11 — However, prevalence estimates varied considerably across some studies, depending on the population and study methodology.
For example, variable prevalence rates were reported between populations of different ethnicities e. Caucasian cohort 13 and More important, prevalence estimates for the more severe and vision-threatening end points, such as PDR and DME, are scarce, due to the small numbers of these cases from individual population-based studies.
Published estimates for VTDR prevalence 17 — 20for example, ranges widely, from 1. Our study provides the first precise estimates for these important clinical subgroups of DR.
